Chapter 8 Create Firewall
Advanced Firewall Configuration Wizard
Configuring Firewall for Remote Access
Creating a firewall can block access to the router that remote administrators may
need. You can specify the router interfaces to use for remote management access
and the hosts from which administrators can log on to Cisco SDM to manage the
router. The firewall will be modified to allow secure remote access from the host
or network that you specify.
Select the outside interface
If you are using the Advanced Firewall wizard, select the interface through which
users are to launch Cisco SDM. This field does not appear in the Basic Firewall
wizard.
Source Host/Network
If you want to allow a single host access through the firewall, choose Host
Address and enter the IP address of a host. Choose Network Address and enter
the address of a network and a subnet mask to allow hosts on that network access
through the firewall. The host or network must be accessible from the interface
that you specified. Choose Any to allow any host connected to the specified
interfaces secure access to the network.
Advanced Firewall Configuration Wizard
Cisco SDM will help you create an Internet firewall by asking you for information
about the interfaces on the router, whether you want to configure a DMZ network,
and what rules you want to use in the firewall.
Click Next to begin configuration.
Advanced Firewall Interface Configuration
Identify the router’s inside and outside interfaces and the interface that connects
